With SO_RCVLOWAT, under memory pressure,
it is possible to enter a state where:
1. We have not received enough bytes to satisfy SO_RCVLOWAT.
2. We have not entered buffer pressure (see tcp_rmem_pressure()).
3. But, we do not have enough buffer space to accept more packets.
In this case, we advertise 0 rwnd (due to #3) but the application does
not drain the receive queue (no wakeup because of #1 and #2) so the
flow stalls.
Modify the heuristic for SO_RCVLOWAT so that, if we are advertising
rwnd<=rcv_mss, force a wakeup to prevent a stall.
Without this patch, setting tcp_rmem to 6143 and disabling TCP
autotune causes a stalled flow. With this patch, no stall occurs. This
is with RPC-style traffic with large messages.

IPA transactions describe actions to be performed by the IPA
hardware. Three cases use IPA transactions: transmitting a socket
buffer; providing a page to receive packet data; and issuing an IPA
immediate command. An IPA transaction contains a scatter/gather
list (SGL) to hold the set of actions to be performed.
We map buffers in the SGL for DMA at the time they are added to the
transaction. For skb TX transactions, we fill the SGL with a call
to skb_to_sgvec(). Page RX transactions involve a single page
pointer, and that is recorded in the SGL with sg_set_page(). In
both of these cases we then map the SGL for DMA with a call to
dma_map_sg().
Immediate commands are different. The payload for an immediate
command comes from a region of coherent DMA memory, which must
*not* be mapped for DMA. For that reason, gsi_trans_cmd_add()
sort of hand-crafts each SGL entry added to a command transaction.
This patch fixes a problem with the code that crafts the SGL entry
for an immediate command. Previously a portion of the SGL entry was
updated using sg_set_buf(). However this is not valid because it
includes a call to virt_to_page() on the buffer, but the command
buffer pointer is not a linear address.
Since we never actually map the SGL for command transactions, there
are very few fields in the SGL we need to fill. Specifically, we
only need to record the DMA address and the length, so they can be
used by __gsi_trans_commit() to fill a TRE. We additionally need to
preserve the SGL flags so for_each_sg() still works. For that we
can simply assign a null page pointer for command SGL entries.

Writes to CURSURFLIVE in TGL are causing IOMMU errors and visual
glitches that are often reproduced when executing CPU intensive
workloads while a eDP 4K panel is attached.
Manually exiting PSR causes the frontbuffer to be updated without
glitches and the IOMMU errors are also gone but this comes at the cost
of less time with PSR active.
So using this workaround until this issue is root caused and a better
fix is found.
The current code is already ready to enable PSR after this exit if
there is not other frontbuffer modifications.
Adding a new if block in psr_force_hw_tracking_exit() instead of reuse
the else/gen8- block because the plan is to revert this workaround
as soon as a better solution is found.

Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:
You can define a local register variable and associate it with a
specified register...
The only supported use for this feature is to specify registers for
input and output operands when calling Extended asm (see Extended
Asm). This may be necessary if the constraints for a particular
machine don't provide sufficient control to select the desired
register.
On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
into the %edx:%eax pair, while all other cases will just use the single
register %eax (%rax on x86-64). While the _ASM_AX actually just expands
to "%eax", note this comment next to get_user() which does something
very similar:
* The use of _ASM_DX as the register specifier is a bit of a
* simplification, as gcc only cares about it as the starting point
* and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
* (%ecx being the next register in gcc's x86 register sequence), and
* %rdx on 64 bits.
However, getting this to work requires that there is no code between the
assignment to the local register variable and its use as an input to the
asm() which can possibly clobber any of the registers involved -
including evaluation of the expressions making up other inputs.
In the current code, the ptr expression used directly as an input may
cause such code to be emitted. For example, Sean Christopherson
observed that with KASAN enabled and ptr being current->set_child_tid
(from chedule_tail()), the load of current->set_child_tid causes a call
to __asan_load8() to be emitted immediately prior to the __put_user_4
call, and Naresh Kamboju reports that various mmstress tests fail on
KASAN-enabled builds.
It's also possible to synthesize a broken case without KASAN if one uses
"foo()" as the ptr argument, with foo being some "extern u64 __user
*foo(void);" (though I don't know if that appears in real code).
Fix it by making sure ptr gets evaluated before the assignment to
__val_pu, and add a comment that __val_pu must be the last thing
computed before the asm() is entered.
